For a variety of vibration triggering, reported theft alarm, intelligent car, electronic building blocks.
Please note that this module triggers a very short Time upon sensing a big shock, not enough to drive the Relay, the data show that some people can be connected directly to the Relay module, the practical application ineffective.

Module wiring instructions:
1.VCC: positive power supply
2.GND: negative one
3.DO: digital signal output
4.AO: With this shock sensor this function is invalid

Module Description:
1. Use of the company's high sensitivity vibration switch SW-18010P default with vibration sensors.
2,.the comparator output signals clean, good waveform, driving ability, than 15mA
3. Working voltage of 3.3V-5V
4, the output form: digital switching output (0 and 1)
5, a fixed bolt hole for easy installation
6, small PCB board size: 3.2cm x 1.4cm
7, using a wide voltage comparator LM393
 
Module Description:
1, when the product does not shock, vibration switch OFF state, the output of high output, the green light does not shine;
2, when the product is shock, vibration switch is turned on instantly, output of low output, the green indicator light;
3, the output can be directly connected to the microcontroller through the microcontroller to detect high and low, thereby detecting whether the environment there is vibration.
